Description

Load balancing method and device

The present invention relates to the field of communications technologies, and in particular, to a load balancing method and device. Background technique

In order to reduce network construction costs and shorten the network construction period, network resources can be shared among multiple operators. The so-called network resource sharing means that multiple operators can share network infrastructure such as computer room facilities and power equipment, and network equipment such as base stations. In the network resource sharing scenario, user equipments of multiple operators can share the same base station or Community.

Specifically, for each cell in the network resource sharing scenario, the actual load of each shared carrier in the cell cannot be accurately determined according to the overall load of the cell, and the actual shared carrier under the cell cannot be accurately determined. The cell resources that can be used, therefore, if the load balancing is still performed according to the currently used load balancing mode, that is, when performing cell load balancing, only the overall load of the cell is considered, only when the overall load of the cell exceeds a certain threshold. Only when some users of the cell are switched to other neighboring cells with relatively low overall load, the overall load for the two cells is light load, but the actual load of a shared carrier A under one cell A has been If the cell resource that can be used by the shared carrier A is severely exceeded, and the actual load of the shared carrier A under another cell B is lower than the cell resource that can be used by the shared carrier A, it can be determined that the cell does not need to be used. The user in A switches to cell B. However, in fact, since the actual load of the shared carrier A in the cell A has seriously exceeded the cell resources that the shared carrier A can use, it is necessary to switch some users belonging to the shared carrier A to resources. In the sufficient cell B, the load balancing of the shared carrier A is realized.

In other words, when load balancing is performed on the cells in the network sharing scenario, the load balancing required by each shared carrier in the cell cannot be accurately implemented, and the load balancing of the cell is implemented. The effect is not good. Summary of the invention

The load information of the first cell includes an overall load of the first cell and a load of the first cell that is actually occupied by a shared operator that can share network resources of the first cell. It should be noted that, in the embodiment of the present invention, the load information may be generally expressed as a cell capacity (0 to 100%) or a cell load (0 to 100%), and the like. limited.

It should be noted that, in the embodiment of the present invention, the second network control node may acquire the load information of the first cell and the network of the at least one shared carrier relative to the first cell. In addition to the shared resource configuration information, the load information of the other cells of the first network control node and the network shared resource configuration information of the at least one shared carrier relative to the other cells may also be acquired, which is also used by the embodiment of the present invention. No restrictions are imposed.

Further, in the embodiment of the present invention, for any one of the at least one shared carrier, the shared resource of the any shared carrier is compared with the network shared resource of the first cell. The set information may include a network shared resource ratio and/or a network shared resource penetration rate of the any shared operator relative to the first cell.

For any shared cell (such as the first cell), the ratio of the network shared resource of the shared carrier to the shared cell refers to the cell resource used by the any shared operator. The ratio of the total cell resources of the shared cell; the network shared resource penetration rate of any of the shared operators refers to any shared operation except the cell resources agreed to by any of the shared operators. The ratio of the cell resource that can be used at most to the total cell resource of the shared cell.

And, for any two cells located in the first network control node and the second network control node, network sharing resource configuration information (including network sharing) of the any shared carrier with respect to any two of the cells The resource ratio and/or the network share resource penetration rate may be the same or different, and the embodiment of the present invention does not limit this.

Specifically, in the embodiment of the present invention, the network shared resource configuration information of each shared carrier relative to each shared cell may be pre-configured by the 0 AM (Operation Administration and Maintenance) device. The OAM device is a device that operates, manages, and maintains network operations by each operator. The OAM device can implement network sharing resource ratios and/or network shared resources of each shared carrier relative to each network control node. The configuration of the information such as the penetration rate; and the network shared resource configuration information that is pre-configured for each shared carrier is generally stored in the corresponding network control node, which is not described in detail in the embodiment of the present invention.

Specifically, in the embodiment of the present invention, the configuration of the network shared resource penetration rate is taken as an example, when the OAM device configures the network shared resource penetration rate of each shared operator relative to each cell of each network control node. , can include the following three situations:

(1), for any network control node, the network shared resource penetration rate of a certain cell relative to the network control node configured for the any shared operator may be applicable to all cells shared by the network, that is, applicable to The serving cell of the network control node is also applicable to the neighboring cell of the network control node. That is, for any two cells located in the first network control node and the second network control node, any shared carrier sees network sharing resources of the two adjacent cells. The transmission rates are identical to each other (^the first network control node and the second network control node are two network control nodes adjacent to each other).

In this case, since the network shared resource penetration rate of any shared operator stored in each network control node relative to a certain cell of the network control node is applicable to all cells shared by the network, in this step 101 The second network control node may use, as the acquired information, the network shared resource penetration rate of any one of the shared operators that are locally stored with respect to any one of the second network control nodes. The sharing of the resource sharing ratio of the network of the first cell with respect to the first cell, so that the network sharing of the any shared carrier relative to the first cell is not required to be obtained from the first network control node. Information such as resource penetration rate to save network transmission resources.

(2), for any network control node, the network shared resource penetration rate of a certain cell of the network control node configured for the any shared operator is applicable only to the serving cell of the network control node, The neighboring cell of the network control node, the network shared resource penetration rate is not applicable.

For example, it is assumed that the cells stored in the network control node A include the serving cells Cell 1 to 3 and the neighboring cells Cell 4 to 6, wherein the serving cells Cell 1 to 3 are located in the network control node A and are directly controlled by the network control node A; 4~6 is located in the network control node B and is directly controlled by the network control node B. At this time, for the network control node A, a certain cell of the network control node A is configured for each shared operator. The network shared resource penetration rate is only applicable to Cell 1-3. For network control Node B, the network shared resource penetration rate of a certain cell relative to the network control Node B configured for each shared operator is only applicable to Cell 4 ~6, therefore, in this step 101, the second network control node needs to obtain, from the first network control node, the network shared resource penetration rate of the any shared operator relative to the first cell, and the like. information.

(3), for any network control node, when configuring the network shared resource penetration rate of each of the shared operators relative to the cells of the network control node, each serving cell of the network control node , are configured with a corresponding network share resource penetration rate.

For example, assume that the cell stored in the network control node A includes the serving cells Cell 1~3 and the neighbors. Cell 4~6, where the service Cell 1~3 is located in the network control node A, and is directly controlled by the network control node A. The Cell 4-6 is located in the network control node B, and is directly controlled by the network control node B, and is directed to the network. The control node A, when configuring the network shared resource penetration rate of each of the shared operators relative to the cells of the network control node A, may configure three separate and the cells for the any shared carrier. 1. The network share resource penetration rate corresponding to Cell 2 and Cell 3, and the network shared resource penetration rates respectively corresponding to the Cell 1, Cell 2, and Cell 3 configured for the any shared carrier may be mutually Not the same. Similarly, for the network control node B, when configuring the network shared resource penetration rate of each of the shared operators relative to the cells of the network control node B, three configurations may be configured for any of the shared operators. The network sharing resource penetration rate corresponding to the Cell 4, the Cell 5, and the Cell 6, respectively, and the network sharing corresponding to the Cell 4, the Cell 5, and the Cell 6 respectively configured for the any shared carrier Resource penetration rates can vary from one to another. At this time, when performing this step 101, the second network control node needs to obtain, from the first network control node, the network shared resource penetration rate of the any shared operator relative to the first cell, and the like. information.

Further, similar to the prior art, in the embodiment of the present invention, the second network control node may obtain the load information of the first cell of the first network control node in the following manner:

Sending a cell load information request message to the first network control node, where the cell load information request message carries the identifier information of the first cell;

Receiving, by the first network control node, a cell load information report message carrying the load information of the first cell, and acquiring load information of the first cell according to the cell load information report message; The cell load information report message is that after the first network control node determines the load information corresponding to the first cell according to the identifier information of the first cell that is carried in the cell load information request message, Two network control nodes sent.

Further, in the embodiment of the present invention, the second network control node may obtain network shared resource configuration information of the at least one shared operator relative to the first cell by: Sending an information acquisition request message to the first network control node, and receiving information obtained by the first network control node that carries the network shared resource configuration information of the at least one shared operator relative to the first cell Obtaining, according to the manner of the message, the network shared resource configuration information of the at least one shared carrier relative to the first cell; or

The information acquisition request message may include at least one of a cell load information request message, a resource status request message, an X2 interface setup request message, and a radio access network information request message; and correspondingly, the information The information acquisition response message corresponding to the request message may include at least one of a cell load information report message, a resource status response message, an X2 interface setup response message, and a radio access network information response message, which is in the embodiment of the present invention. This is not subject to any restrictions.

Further, the information reporting message may include at least one of a resource status update message and a configuration information update message, which is not limited in this embodiment of the present invention. The resource status update message may be sent by the first network control node to the second network control node when determining that the resource status in the first cell is updated; the configuration information update message The first network control node may be sent to the second network control node when determining that the network shared resource configuration information of the first operator in the first cell is updated.

It should be noted that, in the embodiment of the present invention, the information acquisition request message may be a cell load information request message, that is, the second network control node may send a cell to the first network control node. Receiving the information request message, and receiving, by the first network control node, a manner of carrying the cell load information report message of the at least one shared carrier relative to the network shared resource configuration information of the first cell, acquiring the at least A shared network share resource configuration information of the first cell with respect to the first cell. Therefore, the second network control node may report the cell load information of the first cell by using the cell load information report message. The network shared resource configuration information of the at least one shared carrier relative to the first cell is used to save network transmission resources. It should be noted that the second network control node may obtain the at least one share by using other methods before, after, or simultaneously with acquiring the cell load information of the first cell by using the cell load information report message. The network sharing resource configuration information of the first cell is not limited by the embodiment of the present invention.

Step 102: When it is determined that a user belonging to any one of the at least one shared operator in the second cell of the second network control node needs to be handed over, according to the obtained first The load information of the cell and the network shared resource configuration information of the first cell relative to the first cell are used to determine the idle cell resource of the first cell that can be used by any one of the shared operators.

Specifically, in the embodiment of the present invention, when one of the following conditions is met, it may be determined that a user belonging to the any shared operator in the second cell needs to be switched:

(1) The overall load of the second cell is a heavy load, and the load of the second cell actually occupied by any one of the shared operators is not less than that of any one of the shared operators. The cell resources of the second cell (including idle cell resources and non-idle cell resources).

The cell resource of the second cell that can be used by the any shared carrier may be any resource between the first cell resource and the second cell resource, including the first cell resource. And the second cell resource, where the first cell resource is a cell resource determined according to a network shared resource ratio of the any shared carrier relative to the second cell, where the second cell resource is a cell resource determined according to a sum of a network shared resource ratio of the shared cell and a network shared resource penetration ratio of the second cell, and therefore, in the embodiment of the present invention, any one of the shared operations The cell resource of the second cell that can be used by the quotient is generally referred to as the second cell resource, which is not described in detail in the embodiment of the present invention.

For example, the cell 1 and the cell 2 are shared by the operator A and the operator B, and the network sharing resource ratios of the operator A (the any shared carrier) and the operator B relative to the cell 1 and the cell 2 are respectively For 40%, the network shared resource penetration rate is 10%, and the cell load information of cell 1 and cell 2 are as follows: The overall load of the cell 1 is 80%, the load actually occupied by the operator A is 60%, and the load actually occupied by the operator B is 20%;

The overall load of the cell 2 is 50%, the load actually occupied by the operator A is 20%, and the load actually occupied by the operator B is 30%;

At this time, since the overall load of the cell 1 is greater than 60%, it can be determined that the load (60%) of the cell 1 actually occupied by the operator A is greater than the cell 1 that the carrier A can use at most. The cell resource (40%+10%=50%), therefore, it can be considered that the cell 1 is the second cell that satisfies the above condition (1), and it can be determined that the belonging to the operator A in the cell 1 needs to be determined. The user switches.

(2), although the overall load of the second cell is lightly loaded, and the load of the second cell actually occupied by any one of the shared operators is smaller than the maximum usage of the any shared carrier. a cell resource of the second cell, but the overall load of the second cell is greater than the overall load of the first cell, and the load of the second cell actually occupied by the any shared carrier is greater than the The load of the first cell actually occupied by any operator.

For example, the cell 1 and the cell 2 are shared by the operator A and the operator B, and the network sharing resource ratios of the operator A (the any shared carrier) and the operator B relative to the cell 1 and the cell 2 are respectively For 50%, the network shared resource penetration rate is 20%, and the cell load information of cell 1 and cell 2 are as follows:

The overall load of the cell 1 is 60%, the load actually occupied by the operator A is 40%, and the load actually occupied by the operator B is 20%;

The overall load of the cell 2 is 40%, the load actually occupied by the operator A is 10%, and the load actually occupied by the operator B is 30%;

At this time, the overall load of the cell 1 is not more than 60% (light load), and the load of the cell 1 actually occupied by the operator A is smaller than the cell 1 that the carrier A can use at most. The cell resource (50%+20%=70%), and the overall load of the cell 1 is greater than the overall load of the cell 2, and the load of the cell 1 actually occupied by the operator A is greater than the carrier A. The load of the cell actually occupied, therefore, the cell 1 can be considered to satisfy the above condition (2) The second cell can determine that the user belonging to the operator A in the cell 1 needs to be handed over. (3) The overall load of the second cell is medium load or light load, and the load of the second cell actually occupied by any one of the shared operators is not less than that of any one of the shared operators. The cell resource of the second cell used.

For example, the cell 1 and the cell 2 are shared by the operator A and the operator B, and the network sharing resource ratios of the operator A (the any shared carrier) and the operator B relative to the cell 1 and the cell 2 are respectively For 50%, the network shared resource penetration rate is 10%, and the cell load information of cell 1 and cell 2 are as follows:

The overall load of the cell 1 is 70%, the load actually occupied by the operator A is 60%, and the load actually occupied by the operator B is 10%;

The overall load of the cell 2 is 70%, the load actually occupied by the operator A is 50%, and the load actually occupied by the operator B is 20%;

At this time, since the overall load of the cell 1 is greater than 60% (which is a medium load), the load of the cell 1 actually occupied by the operator A is not less than the cell 1 that the carrier A can use at most. The cell resource (50%+10%=60%), therefore, it can be considered that the cell 1 is the second cell that satisfies the above condition (3), and it can be determined that the belonging to the operator A in the cell 1 needs to be determined. The user switches.

It should be noted that, in the embodiment of the present invention, in addition to the foregoing various conditions, there are other various types that may determine that a user belonging to the any operator in the second cell needs to be switched. Condition, if it is determined that the user belonging to the any operator in the second cell is at the edge of the second cell or determining that the wireless signal quality of the second cell is not good, The user of the second cell in the second cell performs the handover, which is not limited in this embodiment of the present invention.

Further, in the embodiment of the present invention, the obtained network shared resource configuration information of the any shared carrier relative to the first cell includes the any shared carrier relative to the first cell. When the network shared resource ratio and the network shared resource penetration rate, the determined idle cell resource Z of the first cell that can be used by any one of the shared operators may be as follows: Z= ( MX ) +min ( N, Y );

The M is a network shared resource ratio of the any shared operator with respect to the first cell, and the X is a load of the first cell actually occupied by the any shared operator, N is a network shared resource penetration rate of the any shared carrier relative to the first cell, where Y is a currently available resource of the first cell.

For example, the cell 1 (first cell) and the cell 2 (second cell) are shared by the operator A and the operator B, and the operator A (the any shared carrier) and the carrier B are opposite to each other. 1 and the network shared resource ratio of the cell 2 is 50%, the network shared resource penetration rate is 20%, and the cell load information of the cell 1 and the cell 2 are as follows:

The overall load of the cell 1 is 40%, the load actually occupied by the operator A is 10%, and the load actually occupied by the operator B is 30%;

The overall load of the cell 2 is 60%, the load actually occupied by the operator A is 40%, and the load actually occupied by the operator B is 20%;

According to the remaining resource calculation principle described in the embodiment of the present invention, the determined idle cell resource Z of the first cell that can be used by any one of the shared operators is (50%-10%) +Min (20) % , 60% ) = 60%.

It should be noted that, in the embodiment of the present invention, if the acquired network shared resource configuration information of the any shared carrier relative to the first cell includes only the any shared carrier, the foregoing The network shared resource ratio of a cell, when determining the idle cell resource Z of the first cell that can be used by any one of the shared operators, the value of N in the above formula can be taken as zero, that is, at this time, It is considered that the network sharing resource penetration ratio of the any shared carrier with respect to the first cell is 0%, which is not described in detail in the embodiment of the present invention.

Step 103: If it is determined that the idle cell resource of the first cell that can be used by any one of the shared operators is greater than a set first threshold, then the user belonging to the any shared carrier is from the second The cell switches to the first cell.

Specifically, in the embodiment of the present invention, the second network control node may use a currently used switching mode to connect users (partial or all users) belonging to any one of the shared operators. The second cell is switched to the first cell, which is not limited in this embodiment of the present invention.

Further, before the user that belongs to the any shared operator is switched from the second cell to the first cell, the method may further include:

And initiating a handover request to the first network control node, and receiving an allow handover response message sent by the first network control node.

Correspondingly, the switching of the user belonging to the any shared operator from the second cell to the first 'j, the area may include:

The allowable handover response message may be that the first network control node determines, according to the handover request, that the idle cell resource of the first cell that can be used by any one of the shared operators is greater than a set second threshold. When sent to the second network control node.

For example, the cell 1 (first cell) and the cell 2 (second cell) are shared by the operator A and the operator B, and the operator A (the any shared carrier) and the carrier B are relatively The network shared resource ratios of cell 1 and cell 2 are respectively 50%, and the network shared resource penetration rate is 20%, respectively, and the cell load information of cell 1 and cell 2 are as follows:

According to the remaining resource calculation principle described in the embodiment of the present invention, the determined idle cell resource Z of the first cell that can be used by any one of the shared operators is (50%-10%) +Min (20) %, 60%) = 60%, and because according to the idle cell resource Z, it can be determined that the idle cell resource of the first cell that the any shared operator can use is greater than 50%, that is, the remaining resources of the cell are sufficient Therefore, a handover request may be initiated to the first network control node, and when receiving the allow handover response message returned by the first network control node, the user belonging to the any shared operator is The second cell switches to the first cell. Further, when the user belonging to the any shared operator in the second cell is handed over to the first cell, the switch to the 10% load is attributed to the any share. After the handover is completed, the cell load information of the cell 1 and the cell 2 can be respectively as follows:

The overall load of the cell 1 is 50%, the load actually occupied by the operator A is 20%, and the load actually occupied by the operator B is 30%;

The overall load of the cell 2 is 50%, the load actually occupied by the operator A is 30%, and the load actually occupied by the operator B is 20%, so that the overall load balancing of the cell 1 and the cell 2 can be further implemented. The load balancing between the operators A in the cell is realized, thereby achieving the effect of improving the load balancing of the cell.

Specifically, the first threshold or the second threshold may be adjusted according to an actual situation, which is not limited in this embodiment of the present invention. Preferably, in the embodiment of the present invention, in order to improve the effect of cell load balancing, and also to avoid resource waste caused by frequent cell handover, the first threshold or the second threshold may be generally set to be relatively high. The value of the embodiment of the present invention is not limited thereto.

Further, in the embodiment of the present invention, the handover request may further carry the handover reason information that the content is load balancing in the network resource sharing scenario, so that the first network control node receives the handover request. The admission decision can be made according to the handover reason information, and then it is determined whether or not to agree to the handover.

Correspondingly, the permission handover response message may be that the first network control node determines, according to the handover reason information carried in the handover request, the idle cell resource of the first cell that can be used by any one of the shared operators. When it is greater than the set second threshold, it is sent to the second network control node. The manner in which the first network control node determines the idle cell resource of the first cell that can be used by the any shared operator and the second network control node determine that the shared carrier can use the The manner of the idle cell resource of the first cell is similar, which is not described in detail in the embodiment of the present invention.

It should be noted that, in various embodiments of the present invention, the network control node involved is not The RNC (Radio Network Controller) and the LTE (Long Term Evolution) eNB (Evolved Node B) can also be GSM (Global System for Mobile Communication). ), WCDMA (Wideband Code Division Multiple Access), LTE, and BSC (Base Station Controller) in Wi-Fi, RNC, eNode B, and AP (Acess Point, Wireless Access Node) The embodiment of the present invention does not limit this. Further, the load balancing method or device involved in the embodiments of the present invention is not only applicable to the same wireless access standard network, but also applicable to two different wireless access standard networks. Any restrictions.

The first embodiment of the present invention provides a load balancing method, where it is determined that the user belonging to any shared operator in the second cell of the second network control node needs to be handed over, according to the first network control node. Determining whether the idle cell resource of the first cell that can be used by any one of the shared operators is greater than a setting, and the network shared resource configuration information of the first cell The threshold, if yes, the user that belongs to the any shared operator is switched from the second cell to the first cell, thereby solving the current existence that cannot be accurately determined according to the overall load of the cell. The load balancing caused by the actual load of each shared carrier and the cell resources that the shared carrier can actually occupy is not accurate, and the effect of cell load balancing is improved.

Embodiment 3:

In the third embodiment of the present invention, the load balancing method according to the first embodiment or the second embodiment of the present invention is further described by taking the first network control node and the second network control node for performing information interaction as an example. As shown in FIG. 3, it is a schematic flowchart of a load balancing method according to Embodiment 3 of the present invention. The load balancing method may include the following steps:

Step 301: The first network control node reports the load information of the first cell of the first network control node and the network shared resource configuration information of the at least one shared operator with respect to the first cell to the second network control node.

The load information of the first cell includes an overall load of the first cell and a load of the first cell that is occupied by a shared operator that can share network resources of the first cell; The network shared resource configuration information of the at least one shared carrier relative to the first cell may include a network shared resource ratio and/or a network shared resource of the any shared carrier relative to the first cell. Permeability.

Specifically, similar to the prior art, in the embodiment of the present invention, the first network control The node generally reports the load information of the first cell to the second network control node in the following manner:

Determining, according to the identifier information of the first cell, the load information corresponding to the first cell, and reporting, by using the second network control node, the cell load information that carries the load information of the first cell And reporting, to the second network control node, load information of the first cell.

The first network control node may report the network shared resource configuration information of the at least one shared operator to the first cell to the second network control node by:

Receiving the information acquisition request message sent by the second network control node, and returning, to the second network control node, information acquisition that carries the network shared resource configuration information of the at least one shared operator relative to the first cell And responding to the message, reporting, by the second network control node, the network shared resource configuration information of the at least one shared operator relative to the first cell.

The information acquisition request message includes at least one of a cell load information request message, a resource status request message, an X2 interface setup request message, and a radio access network information request message. The information report message includes at least resources. The embodiment of the present invention does not limit the one or more of the status update message and the configuration information update message.

It should be noted that, in the embodiment of the present invention, any one of the shared operators is relatively free for any two cells located in the first network control node and the second network control node. The network shared resource configuration information of the two cells may be the same as each other. Therefore, when the foregoing situation is met, the first network control node may not report the at least one shared carrier to the second network control node. Network sharing resource configuration information for a cell to save The network transmission resource is not described in detail in the embodiment of the present invention.

Step 302: When the second network control node determines that the user belonging to any one of the at least one shared carrier in the second cell needs to be handed over, according to the acquired first cell The load information and the network shared resource configuration information of the first cell relative to the first cell are determined, and the idle cell resource of the first cell that can be used by the any shared operator is determined.

The time points are different from each other. Therefore, the available idle cell resources are usually different from each other. Correspondingly, in order to distinguish between the first threshold and the second threshold, the embodiment of the present invention does not limit the present invention.

Step 305: The second network control node switches the user belonging to the any shared operator from the second cell to the first cell according to the allowed handover response message returned by the first network control node.

Specifically, in the embodiment of the present invention, the second network control node may use a currently used switching mode, and the user (partial or all users) belonging to the any shared carrier is from the second The cell is switched to the first cell, which is not limited in this embodiment of the present invention.
